The rose rosette task force compiled the rose virome in 2016 and twenty-four viruses have been reported worldwide to infect roses. These viruses can reduce yields of garden roses because they cause damage to roses even before visible symptoms develop. Therefore, early viral infections may not be diagnosed until symptoms break out or fully develop in the plant. Common and frequently used detection of viral diseases affecting roses are serologically based, such as ELISA, or alternatively, lateral flow devices.

In the field of plant physiological ecology, people are usually interested in how leaf carbon and water dynamics determine whole plant performance, including growth and reproduction, with stems being the organ responsible for water transport and mechanical support. In many plants from arid and semi-arid ecosystems in both temperate and tropical regions, green photosynthetic stems have evolved in many species, possibly as a response to water shortage at least during one period of the year, yet the possible advantages that green stems confer to such species remain unclear.

Lilium (commonly known as lily) is one of the most important bulbous flower genera belonging to the family Liliaceae, and is native to temperate regions of the northern hemisphere. It is used for cut flower production, pot plant production and landscaping purposes. Each year the interest in lilies increases around the world. Presently they hold the fourth position among cut flowers in world flower trade. Pollen is a unique plant tissue that potentially can be used and manipulated to the advantage of the geneticist, breeder, physiologist and germplasm curator.

Jens Mincke obtained his MSc in Chemistry and Bioprocess Technology at Ghent University in 2013 and obtained a second MSc in Biomedical Engineering at Ghent University & Vrije Universiteit Brussel in 2015. Jens is currently conducting PhD research under the supervision of Prof. Dr. ir.

Lili Yang is a doctoral student at the Northwest A & F University in China. Her major is plant nutrition and her research is focused mainly on fruit nutrition management, especially of kiwifruit.

India contributes 69% of global mango production. However, availability of fruit in India meets only 50% of demand. In order to overcome the problems of post-production losses, several strategies, such as the best harvesting and handling practices, are being promoted. However, the recommended practices are not being adopted because of practical difficulties. This situation requires a simple and practical solution to a challenging problem.

This project investigated the effects that different rates of nitrogen fertigation had on red drupelet disorder expression in commercial blackberries. Red drupelet disorder (sometimes known as red drupelet reversion or reddening) is a postharvest physiological disorder that causes fruit, which is black at harvest, to revert to a red colour following cold storage. This causes a mottled appearance on the fruit that is off-putting to the consumer and can render fruit unmarketable in some cases, causing significant financial loss to producers.

Consumption of African leafy vegetables (ALVs) has increased in Kenya, especially within urban and peri-urban areas. ALVs, such as vegetable amaranth (Amaranthus cruentus L.), are rich in bioactive compounds, e.g. protein, minerals, vitamins, dietary fiber, carotenoids and phenolic compounds, which play an important role in health promotion. However, ALVs are highly perishable; hence they suffer significant postharvest losses. The use of ultraviolet light C (UV-C) is gaining interest in improving postharvest quality and hygienic status of fruits and vegetables.

Since 1991, fruit and vegetable production has been expanding in Uzbekistan. Although national supply should be sufficient for the population to receive recommended daily servings, fruit and vegetable intake remains inadequate, with a strong seasonal pattern. The horticultural supply in Uzbekistan is characterized by seasonal fluctuations which impact prices and other factors that then affect decisions on consumption. Detailed analysis of such factors was the focus of this study.

Urban horticulture pioneer Lufa Farms has just finished a third highly automated greenhouse in the Montreal borough of Anjou (Canada). Canada's Prime Minister Justin Trudeau was there to see it in full production. The new 63,000 square foot rooftop greenhouse is a milestone in polyculture efficiency and produces over 40 varieties of urban-grown greens and vegetables throughout the year.
